Technical Committee Summary—April 17, 2018

The O’Hare Noise Compatibility Commission Technical Committee met on Tuesday, April 17 at the Mount Prospect Village Hall. The Chicago Department of Aviation and Federal Aviation Administration staff updated members on the permanent and portable noise monitors, updated noise monitor fact sheets and charts, the noise complaint system, and the Interim Fly Quiet status.

Noise Monitors

Itasca noise monitor #44 and Norridge noise monitor #18 have been commissioned. Bensenville monitor will be operational in the future.

The process for three Chicago monitors located in Wards 40, 41 and 39 has started with a targeted completion date of June 2018. Ward 40 monitor location has been determined to be near Mather High School at the Park District.

The February average for long-term portable noise monitors measured 59.2DNL in Chicago and 61.3DNL in Itasca. Permanent noise monitor #44 will now capture noise for the Itasca area.

Currently, there is one municipal portable noise monitor deployed in Bloomingdale through July 2018.

On January 27th the CDA added a CAPTCHA feature to the noise complaint system. It requires checking boxes to complete the complaint.The first completed month with the new CAPTCHA system was tabulated in the February ANMS report at the April ONCC general meeting.

Interim Fly Quiet Report

Amy Hansen, environmental specialist for the FAA, reported that the agency received the City of Chicago’s submittal for contract approval of the third-party consultant for the Interim Fly Quiet (IFQ) environmental impact study. The FAA works with airport sponsors who take direction from the FAA. She estimates that once the scope of services has been approved and the contract signed, the process will take approximately one year to complete. The FAA will submit a draft report of the study, hold several public workshops to address resident comments and then present a final environmental report. Once approved, the IFQ will be in effect until the commissioning of Runway 9C/27C in fall 2020.
